    2. 3. “ WE ARE WHAT WE EAT”
    3. 4. DEFINITIONS <ul><li>NUTRITION: </li></ul><ul><li>W.H.O: the science of food and its relationship to health. </li></ul><ul><li>It is concerned primarily with the part played by the nutrient in body growth, development and maintenance. </li></ul><ul><li>NIZEL: the science which deals with the study of nutrients and foods and their effects on the nature and function of the organism under different conditions of age, health and disease. </li></ul><ul><li>DCNA 2003: the science, how the body utilizes food to meet the requirement for development , growth, repair and maintenance. </li></ul>
    4. 5. <ul><li>DIET </li></ul><ul><li>Nizel (1989): total oral intake of a substance that provides nourishment & supply. </li></ul><ul><li>P.M Randelph(1981) : It is the total intake of substance that furnish nourishment & or calories to the body. </li></ul>
    5. 6. <ul><li>BALANCED DIET: is the one which contains varieties of foods in such quantities and proportion that are needed for energy. </li></ul><ul><li>RECOMMENDED DIETARY ALLOWANCE : nutrient amounts in excess of what 98% of the population requires to maintain health. </li></ul>
    6. 7. WHY do we need nutrition ?
    7. 8. ENERGY NEEDS OF THE BODY <ul><li>Calculated by the sum of 4 factors: </li></ul><ul><li>Basal metabolism </li></ul><ul><li>Energy for physical activity </li></ul><ul><li>Energy used for body heat </li></ul><ul><li>Specific dynamic action of food (SDA) </li></ul>
    8. 9. CALORIES AND ENERGY <ul><li>Energy made available to body in 4 basic forms: </li></ul><ul><li>CHEMICAL - for synthesis of new compounds </li></ul><ul><li>MECHANICAL - for muscle contraction </li></ul><ul><li>ELECTRICAL - for brain and nerve activity </li></ul><ul><li>THERMAL - for regulation of body temperature </li></ul>
    9. 10. Functions of the food * <ul><li>Physiological function </li></ul><ul><li>Social function </li></ul><ul><li>Psychological function </li></ul><ul><li>PHYSIOLOGICAL FUNCTION : </li></ul><ul><li>supply energy. </li></ul><ul><li>build & maintain the cells & tissues </li></ul><ul><li>regulate body process - movement of fluids </li></ul><ul><li>control acid & base balance </li></ul><ul><li>coagulation of blood </li></ul><ul><li>activation of enzyme </li></ul>
    10. 11. <ul><li>SOCIAL FUNCTIONS OF FOOD : </li></ul><ul><li>Acts as media to develop social rapport in the society. </li></ul><ul><li>Is an integral part of social phase of university living. </li></ul><ul><li>PSYCHOLOGICAL FUNCTION OF FOOD : </li></ul><ul><li>Satisfies of certain emotional needs. </li></ul><ul><li>Used to express feelings: </li></ul><ul><li>a) Token of friendship </li></ul><ul><li>b) Serving of favorite foods - expression of special </li></ul><ul><li>attention. </li></ul><ul><li>c) Withholding of wanted foods - punishment. </li></ul>
    11. 12. BASAL METABOLIC RATE <ul><li>Basal metabolic rate (BMR) – the number of calories expended by the organism per square meter of body surface per hour (kcal/m 2 /hr). </li></ul>
    12. 13. NORMAL BMR VALUES FOR DIFFERENT AGE GROUP AND SEX . Age in yrs Male kcal female kcal 5 53 51 10 49 46 15 46 40 20 41 36 30 39 36 40 38 36 50 37 34 60 35 33
    13. 14. Recommended Dietary Allowance <ul><li>RDA – nutrient amounts in excess of what 98% of the population requires to maintain health ; they are not minimum requirements or optimal intakes for all people. </li></ul><ul><li>Average daily intake energy and nutrient level intake estimates for healthy populn , through consumption of variety of foods. </li></ul><ul><li>Food & nutrition board --- Dietary reference intakes. </li></ul>
